中文摘要	为探讨抗旱种草技术,观测对比分析了春季覆膜不同垄宽0,20,30,40,50cm沟播紫花苜蓿(Med-icago sativa L)的生产性能.结果表明,随覆膜集水补墒不足程度的增加,由于细胞生长减缓引起对同化物的需求也随之减少,故对试验苜蓿生理发育过程的影响不大.早期出苗生长期不等的个体,在单株发育变化上遵循季节生长能量功能分配生物学特性,并与对照有不同程度的差异;在单株产量和根颈发育直径方面,不同膜幅处理之间呈现明显的差异.考虑试验区降水年际变率和行内增苗对个体发育的影响,水土保持草地或种子田应选择30和40cm的覆膜垄宽为宜,收获鲜草的草地以20,30cm的覆膜垄宽抓苗较好
英文摘要	To explore the drought-resistant technique of grass planting, the production characters of alfalfa(Medicago sativa L) trench planted in spring with the ridge width of 0cm, 20cm, 30cm, 40cm and 50cm were analyzed. The results showed that the effect of different treatments to test alfalfa on physiological growth was little as the degree of gathering rainwater to moisten soil dropped. Because the growth retard cells resulted in the less demand of assimilation. The development of the early seedlings was different with the control. In the planting year, there were significant differences in the yield and root-neck diameter among the treatments. To consider the effect of the yearly rainfall and the increasing plants in row on the development of plants,the ridge width of 30 cm and 40 cm was suited for soil and water conservation or seed, 20 cm and 30 cm for grass
